Protecting welding parameters from unauthorised access

To protect against unauthorised or unintentional adjustment of the welding parameters on the machine,
the control input can be locked with the aid of a key switch.

Welding programs

The welding machine has 16 programs, which can be accessed during the welding process, e.g. using an
up/down torch.
In each selected welding task (JOB), see the "Selecting the welding task" chapter, 16 programs can be
set, saved and accessed. In program "0" (default setting), the welding current can be set infinitely across
the whole range. In programs 1–15, 15 different welding currents can be defined.
Operating mode and pulse function can also be defined for programs 1–15, if the connected RINT X12 or
BUSINT X11 interface is in JOB mode. If the interfaces are not in JOB mode, operating mode and pulse
function are predefined by the interfaces.
Example:
Program number
1
2
The operating mode cannot be changed during the welding process. If the process is started with
program 1 (non-latched operating mode), program 2, despite being set to latched operating mode, will
apply the setting of start program 1 until the end of the welding process.
Pulse function (pulses off, pulses on) and welding currents will be applied from the relevant programs.
Changes made to the other welding parameters during the course of the program have
the equivalent effect on all programs.
Any change to the welding parameters is saved immediately in the JOB!
